I think you have a point. I do envy those people that stumble upon this game with this game from now on. The game as a whole is very generous for new cummers ...ahem new comers.
I imagine which would be my experience if I found this game today instead of pre-pig town.
I mean, lets take a look at my first time playing this game... I got some enjoyment from the first three stages and the 13 to 15 scenes you get at them, then I came buckets at the village, and more buckets at the sewer (boy , I love the small slugs sequence, the medium slugs sequence, and the big slug sequence like a lot...the two bosses are nice too), then had a nice time on the cathedral, not as much as in the two stages before, but it was nice and very generous with the amounts of scenes. That was already a great experience at that point...
but imagine! right after getting the credits finding you have TWO bonus stages ! I would have deshidrateted from cumming all that much in that little time. The laboratory has some nice stuff, and the pig den is buckets-of-cum-inducing.
The game as a whole is very generous, but it would have benefited from a more speedy updating... of course, at the end of the day I am happy to know this game
